I have a sound card Creative Soundblaster X-Fi HD (USB) which works perfectly in Windows 7. However, it doesn't work well on Ubuntu 12.10. Whenever I switch on my computer it boots in any of these three states:
The sound card is not "fully" recognized (it shows that it is connected but I cannot get in the level-meter using
alsamixerin the terminal).
The soundblaster is fully recognized, I have access at all parameters, but it emits no sound.
It works perfectly (about one out of five times).
I checked the others topics, it seems that nobody has found a solution so far...
What kind of command could I tip in order to "see" the difference between these three cases? I guess the problem comes from the "initialization" of the sound card, but I notice no change in the configuration/alsamixer between the second and the third case.
How can I make sure it is initialized correctly and working all the time? Any help on this would be appreciated!
